SHOE-POUNDING MACHINE.

Application filed April 16,

To all whom it may concern:

Be it known that I, ALBERT F. FRoUssaRD, a citizen of the United Statesof America, residing at the city of St. Louis, State of Missouri, UnitedStates of America, have invented a certain new and useful Shoe- PoundingMachine, of which the following is such a full, clear, and exactdescription as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, formin part of this specification.

My invention relates to a shoe pounding machine such as is used forforming the soles of shoes and one object of my invention is to providea machine in which the hammer will be actuated in a straight line and inwhich the mechanism will be as simple and compact as possible. Anotherob ect of my invention is to provide means for ad usting the angle ofthe shoe hammer so as to apply the blows of the hammer most effectivelyto the sole of the shoe.

In the accompanying drawings which illustratev one form of shoe poundingmachine made in accordance with my invention, Figure 1 is a sideelevation, Fig. 2 is a front elevation, Fig. 3 is a top plan view, andFig. 4 is a section taken on the line 11 of Fig. 3.

5 indicates a standard provided with a table 6 to which are secured apair of bearings 7 Journaled in the bearings 7 is a shaft 8 carrying aloose pulley 9 and a tight pulley 10 for driving the said shaft. Theforward end of the shaft 8 is provided with a stud 11 on which a cam 12isremovably secured by means of a nut 13. In the drawings, the cam 12 isshown as provided with three cam faces. The number of cam faces,however, may be varied to vary the rapidity with which the hammer isactuated. Secured to the table 6 at right angles to the bearings 7 is abearing 15 in which is slidingly mounted a rod 16 provided on its rearend with a rounded face 17 adapted to coact with the cam faces on thecam 12. The rod 16 is held in position by means of a pin 18 passingthrough a slot 19 in the said rod. 20 is an arm which is secured to theSpecification of Letters Patent.

bar 16 by means of a pin 21. This arm 20 carries an adjusting screw 22adapted to strike against a lug 23 carried on the bearing 15 and lockedin position by means of a lock nut 24:.

27 is a shoe hammer pivotally secured to the bar'16 by means of a bolt28 and adapted to be locked in its various angular positions by means ofa nut 29 on the said bolt 28. Formed in the shoe hammer 27 is a recess30 to receive the flame for heating the working face 31 of the'hammer.The heating is accomplished by means of a Bunsen burner 32 verticallyadjustable in an arm 33 by means of a set screw 34. The arm 33 ispivotally secured to a lug 35 upon the table 6 by means of a wing nut 36so that the arm 33 may be adjusted to accommodate the burner to thevarying positions of the shoe hammer 27.

In using my machine, the sole of the shoe to be shaped is held againstthe face 31 of the shoe hammer, the force of the blows being regulatedby the pressure of the shoe against the shoe hammer. As the shoe hammeris actuated in a straight line the blows are most effectively applied tothe sole and the angular position of the hammer may be varied so as toaccommodate different positions of the shoe. The amount of movementimparted to the hammer may be varied by moving the adjusting screw 32.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1.' In a shoe pounding machine, the combination with a rotary member, ofa cam carried by said rotary member, a sliding member actuated from saidcam, and a shoe hammer adjustably pivoted to said sliding member toswing in a vertical plane parallel to the line of travel of the slidingmember.

2. In a shoe pounding machine, the combination with a rotary member, ofa cam carried by said rotary member, a sliding member actuated from saidcam, a shoe hammer pivotally carried by said sliding heating device forthe shoe hammer carried by said arm.

3. In a shoe pounding machine, the combination with a rotary member, ofa cam 5 carried by said rotary member, a sliding member actuated fromsaid cam, a shoe hammer adjustably carried by said sliding member, a gasjet pivotally mounted to cooperate With said shoe hammer, means foradjusting said jet on its pivot, and means 10 for adjusting said jetlongitudinally.

In testimony whereof, I have hereunto set my hand and affixed my seal.
